Frmer White House strategist called the infamous Trump Tower meeting “treasonous,” according to a new book.

Steve Bannon suggested President Donald Trump was aware of Donald Trump Jr.’s meeting with Russian operatives at Trump Tower in June 2016 ― because he met with them that day, too, according to an explosive new book by acclaimed journalist Michael Wolff.

The former White House strategist was quoted by Wolff as saying there was “zero” chance Trump Jr. didn’t walk the Russian meeting attendees “up to his father’s office on the 26th floor.”

SIREN: "Steve Bannon was certain that after the (July 2016 Trump Tower) meeting, Trump, Jr. had taken the participants to see his father," per excerpts from new Michael Wolff book, "Fire & Fury."Trump has claimed he was unaware any meeting with Russians took place.

NEW: Here's the Bannon quote regarding the July 2016 Trump Tower meeting: "The chance that Don Jr. did not walk these Jumos up to his father’s office of the 26th floor is zero,” per "Fire & Fury." (pg. 255)

Wolff met with Bannon during the nine months he was granted far-reaching access to the West Wing and senior administration officials to write a tell-all book about the White House, Fire and Fury, set for release on Jan. 9.

The revelations appeared to contradict Trump’s repeated claims that he was unaware his eldest son, as well as his son-in-law Jared Kushner, had met with the Russians.

Bannon also dubbed the infamous Trump Tower meeting as “treasonous” and “bad shit,” according to Wolff. The far-right icon mocked Trump Jr. and Kushner for taking the meeting in hopes of acquiring dirt on Hillary Clinton, Trump’s political opponent in the 2016 presidential race, as first revealed by The New York Times in July.

“The three senior guys in the campaign thought it was a good idea to meet with a foreign government inside Trump Tower in the conference room on the 25th floor — with no lawyers,” Bannon told Wolff, according to The Guardian, which obtained a copy of the book.

“Even if you thought that this was not treasonous, or unpatriotic, or bad shit, and I happen to think it’s all of that, you should have called the FBI immediately,” he added.

Bannon predicted special counsel Robert Mueller’s investigation into possible collusion between Trump’s 2016 campaign and the Russian government will focus on money laundering.

“This is all about money laundering,” Bannon told Wolff. “Mueller chose [senior prosecutor Andrew] Weissmann first and he is a money-laundering guy. Their path to fucking Trump goes right through Paul Manafort, Don Jr and Jared Kushner … It’s as plain as a hair on your face.”

“The Kushner shit is greasy,” Bannon said. “They’re going to go right through that. They’re going to roll those two guys up and say play me or trade me.”

Four Trump associates have been indicted in connection to the probe, including former national security adviser Michael Flynn and former Trump campaign chairman Paul Manafort, who also attended the Trump Tower meeting. Manafort was indicted by a grand jury in October on charges of conspiracy and money laundering.

“They’re going to crack Don Junior like an egg on national TV,” Bannon said, adding that the White House should reconsider its apparent lack of concern over the Mueller investigation. “They’re sitting on a beach trying to stop a Category Five.”
